MARKER FOR COBN-PLANTERS.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed December 13, 1920. Serial No. 430,310.

To aZZ whom it may concern:

Be it known that I, Srno'rrinn lVA'rsoN, a citizen of the United States, residing at Gallatin, in the county of Sumner and State of Tennessee, have invented new and useful Improvements in Markers for Corn-Planters, of which the following is a specification.

This invention relates to a marker for corn planters, and the invention consists in the novel construction, combination and arrangement of elements hereinafter described and claimed.

In the drawings, Figure 1 is a top plan view showing the marking device applied to a planter, and Fig. 2 is a fragmentary view,

21, and mounted on this shaft is a sprocket wheel 22, driving chain 23, the chain passing around sprocketwheel 24:, shaft 14 of the marking device. A smaller sprocket wheel 25 may be used for producing a drive at a higher speed.

Radially connected with each end of the shaft 1 1 is a T-connection having a bore 27 through which arm 28 of the marking clevice passes. Springs 29 encircle arm 28 on opposite sides of the T-connection and their outer ends being properly retained the arm is permitted to move transversely of the shaft 14-, with the result that the marking devices are allowed to yield in passing over uneven ground.

Each marking device comprises a cupshaped element 30, connected by a brace 31 with arm 28, this brace comprising a central apertured element and a plurality of outwardly extending arms as shown. The cupshaped device 30 is especially effective in making a clear mark.

Mounted on the shaft 14 is a ratchet wheel 35 engaged by a pawl 36 mounted on lever 37, or more definitely speaking between elements 37 constituting apertured forked ends, these members 37 shaft 14 on opposite sides of the ratchet wheel.

From the foregoing it will be observed that owing to the simplicity of the device and the direct and positive connection be tween the operative elements, reliability in operation is assured. While I have referred to certain minor details of construction, it is obvious that changes in such details may be made Within the scope of the appended claims.

What is claimed is 1. A marking device for a planter, comprising a cup-shaped element, an apertured brace connected therewith and extending across the open end of the cup, and a supporting member, said apertured brace permitting of the mounting of the cup on the supporting member.

2. In a device of the class described, a shaft and means for driving the shaft, arms mounted perpendicularly of the shaft at opposite ends thereof, and cup-shaped marking devices mounted on the arms and having their open ends toward the shaft, each marking device including a transverse brace through which the shaft passes, said brace acting as a mounting device.

In testimony whereof I afhx my signature.

STROTHER WATSON.
